BASIC FUNCTIONS OF A TORQUE CONVERTER:

The torque converter takes the place of a conventional clutch and pressure plate used with stick shift transmissions. It is nothing more than a centrifugal pump (impeller) which could be compared to a fan, which drives another fan (turbine) that is connected to the rear wheels. The force that turns the turbine is referred to as torque. This results from the impeller expelling a column of fluid rotating counter clockwise (viewed from the rear of the vehicle) as it enters the turbine runner. It is very similar to a fire hose aimed at a wall that creates a rearward force on the hose. This rearward force from the column of oil rotating from one fan to the other and finding the exact strike point is what creates torque and turns the turbine. Finding the strike point of the rotating oil is achieved by changing the angle of the fins of the impeller. As torque increases, the vehicle begins to accelerate at a higher rate. One of the ways that stall can be raised or lowered, is by changing the angle of the direction of flow entering the turbine runner. Another is by changing the diameter of the converter itself.
